Here is the controller for adding and the callback: public function add() { if ($this->ion_auth->logged_in()): //validate form input $this->form_validation->set_rules('title', 'title', 'trim|required|max_length[66]|min_length[2]'); // link url $this->form_validation->set_rules('link', 'link', 'trim|required|max_length[255]|min_length[2]'); // optional content $this->form_validation->set_rules('content', 'content', 'trim|min_length[2]'); $this->form_validation->set_rules('userfile', 'image', 'callback_validate_upload'); $this->form_validation->set_error_delimiters('<small class="error">', '</small>'); // if form was submitted, process form if ($this->form_validation->run()) { // add pin $pin_id = $this->pin_model->create(); $slug = strtolower(url_title($this->input->post('title'), TRUE)); // path to pin folder $file_path = './uploads/' . $pin_id .

  • Is there a better way to write this .htaccess directive?

    - by Bill H
    I want all css, javascript, and image file requests, that are named like this "filename.12345.css" to be re-routed to "filename.css". The ".12345" part will always be numbers and the length can be anywhere from 11 - 15 characters. This directive seems to work OK but I want to make sure there is no error in my logic. RewriteRule ^(.+)\.(.+)\.(js|css|jpg|gif|png)$ $1.$3 Any help would be greatly

  • C: reading file and populating struct

    - by deostroll
    Hi, I have a structure with the following definition: typedef struct myStruct{ int a; char* c; int f; } OBJECT; I am able to populate this object and write it to a file. However I am not able to read the char* c value in it...while trying to read it, it gives me a segmentation fault error. Is there anything wrong with my code: //writensave.c #include "mystruct.h" #include <stdio.h> #include <string.h> #define p(x) printf(x) int main() { p("Creating file to write...\n"); FILE* file = fopen("struct.dat", "w"); if(file == NULL) { printf("Error opening file\n"); return -1; } p("creating structure\n"); OBJECT* myObj = (OBJECT*)malloc(sizeof(OBJECT)); myObj->a = 20; myObj->f = 45; myObj->c = (char*)calloc(30, sizeof(char)); strcpy(myObj->c, "This is a test"); p("Writing object to file...\n"); fwrite(myObj, sizeof(OBJECT), 1, file); p("Close file\n"); fclose(file); p("End of program\n"); return 0; } Here is how I am trying to read it: //readnprint.c #include "mystruct.h" #include <stdio.h> #define p(x) printf(x) int main() { FILE* file = fopen("struct.dat", "r"); char* buffer; buffer = (char*) malloc(sizeof(OBJECT)); if(file == NULL) { p("Error opening file"); return -1; } fread((void *)buffer, sizeof(OBJECT), 1, file); OBJECT* obj = (OBJECT*)buffer; printf("obj->a = %d\nobj->f = %d \nobj->c = %s", obj->a, obj->f, obj->c); fclose(file); return 0; }

  • Listfield layout question - blackberry

    - by Kai
    I'm having an interesting anomaly when displaying a listfield on the blackberry simulator: The top item is the height of a single line of text (about 12 pixels) while the rest are fine. Does anyone know why only the top item is being drawn this way? Also, when I add an empty venue in position 0, it still displays the first actual venue this way (item in position 1). Not sure what to do. Thanks for any help. The layout looks like this: ----------------------------------- | *part of image* | title | ----------------------------------- | | title | | * full image * | address | | | city, zip | ----------------------------------- The object is called like so: listField = new ListField( venueList.size() ); listField.setCallback( this ); listField.setSelectedIndex(-1); _middle.add( listField ); Here is the drawListRow code: public void drawListRow( ListField listField, Graphics graphics, int index, int y, int width ) { listField.setRowHeight(90); Hashtable item = (Hashtable) venueList.elementAt( index ); String venue_name = (String) item.get("name"); String image_url = (String) item.get("image_url"); String address = (String) item.get("address"); String city = (String) item.get("city"); String zip = (String) item.get("zip"); EncodedImage img = null; try { String filename = image_url.substring( image_url.indexOf("crop/") + 5, image_url.length() ); FileConnection fconn = (FileConnection) Connector.open( "file:///SDCard/Blackberry/project1/" + filename, Connector.READ); if ( !fconn.exists() ) { } else { InputStream input = fconn.openInputStream(); byte[] data = new byte[(int)fconn.fileSize()]; input.read(data); input.close(); if(data.length > 0) { EncodedImage rawimg = EncodedImage.createEncodedImage(data, 0, data.length); int dw = Fixed32.toFP(Display.getWidth()); int iw = Fixed32.toFP(rawimg.getWidth()); int sf = Fixed32.div(iw, dw); img = rawimg.scaleImage32(sf * 4, sf * 4); } else { } } } catch(IOException ef) { } graphics.drawText( venue_name, 140, y, 0, width ); graphics.drawText( address, 140, y + 15, 0, width ); graphics.drawText( city + ", " + zip, 140, y + 30, 0, width ); if(img != null) { graphics.drawImage(0, y, img.getWidth(), img.getHeight(), img, 0, 0, 0); } }

  • What rendering services are available to convert URLs to images?

    - by tangens
    I know some services that encode the description of an image inside on an URL. For example: yuml.me for drawing UML Diagrams: or www.codecogs.com for rendering LaTeX equations: I really like these services to use them inside my javadoc to illustrate the documentation. On stackoverflow.com it's a bit tricky to encode these URLs, see my request at meta.stackoverflow.com. Question Are there any other rendering services that are useful for documenting source code?
